FIELD

The present disclosure relates to streaming multimedia data. Particularly, but not exclusively, the present invention relates to a method and a device for streaming multimedia data over multiple network interfaces.

BACKGROUND

Streaming is a process of delivering media to an end user in a sequence. Live streaming is a process of streaming media in real-time by collecting media files from a provider. Media may be audio files or video files. Live video streaming is very popular as various media devices support downloading the media files in real-time. A video can be streamed in many qualities, for example, 144p, 240p, 360p, 480p, 720p, 1080p, etc. Here, video streaming of qualities 144p, 240p, 360p and 480p provide low picture quality and require less Internet bandwidth and low data rate for downloading the media files. Video streaming of qualities 720p, 1080p and higher resolution video streaming provide high picture quality and require high bandwidth and high data rate for downloading the media files.

In a scenario, where a user may require high quality of video streaming but has access to a poor Internet connection, traditional systems automatically decrease quality of video streaming and provide a quality of video streaming such that streaming is not interrupted. Here, video quality is compromised. Thus, the user may not get the desired quality of video streaming.

Developments are made in video streaming systems for providing the user with high quality video streaming without interruption. Conventional systems use multiple network interfaces for downloading media files for providing high quality video streaming. Here, multiple network interface may be cellular network, Wireless Fidelity (Wi-Fi) network and Bluetooth tethering. The conventional systems download the media files on each of the multiple interfaces. The media files are divided into one or more packets. Here, the one or more packets are received from at least one network interface from the multiple interfaces. However, a packet is received from each of the network interfaces, thus causing repetition of the one or more packets. Also, additional memory may be required to store the one or more packets. Thus, the conventional systems may not be feasible for applications having memory constraints. Also, device transmitting the one or more packets and device receiving the packets may consume more power for transmitting and receiving the same packets respectively.

The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

FIG. 1A shows an exemplary block diagram of a media device 100 for adaptive streaming of multimedia data. FIG. 1A shows the media device 100 comprising a network interface 101 ₁, a network interface 101 ₂, . . . a network interface 101 _(N), a media buffer 102 and a media player 103. The media device 100 is connected to a media server 104. The network interface 101 ₁, a network interface 101 ₂, . . . a network interface 101 _(N) can be collectively represented as one or more network interfaces 101 in the present disclosure. Further, the media device 100 is connected to the media server 104. The media server 104 transmits the multimedia data as one or more packets to the media device 100. The media device 100 requests the media server 104 for the one or more packets through the one or more interfaces 101. The one or more packets received from the media server 104 are collected in the media buffer 102 of the media device 100. In an embodiment, the media buffer 102 collates the one or more packets in sequence. Further, the sequenced one or more packets are provided to the media player 103 for streaming the multimedia data.

In an embodiment, let us consider a multimedia data is divided into 10 packets. Further let us consider that the media device 100 comprises three network interfaces 101. The media device 100 determines one or more bandwidth parameters of each of the one or more interfaces 101. In this illustration, the media device 100 calculates bandwidth size and bandwidth speed of each of the three network interfaces 101 and allocates specific packets from the one or more packets to each of the three network interfaces 101. The allocation of the one or more packets is illustrated in FIG. 2. Considering the 10 packets in a sequence as shown in FIG. 2, let the media device 100 allocate first packets P1 and P2 to first network interface 101 ₁, subsequent 3 packets, P3, P4 and P5 to second network interface 101 ₂ and packets P6, P7, P8, P9 and P10 to third network interface 101 ₃. Further, the allocated packets are requested over respective one or more network interfaces 101, i.e., the packets P1 and P2 are requested over the first network interface 101 ₁. Likewise, the packets P3-P5 are requested over the second network interface 101 ₂ and the packets P6-P10 are requested over the third network interface 101 ₃. In general, if N is the total number of packets, then the first network interface 101 ₁ may be allocated 1_(st) packet to (N−X)_(TH) packet, where X is an integer. Similarly, the second network 101 ₂ may be allocated (N−X+1)_(TH) packet to (N−Y)_(TH) packet, where Y is an integer for Y<X. Likewise, for N_(th) network interface 101 _(N) may be allocated (N−Z+1)_(TH) packet to N_(TH) packet, where Z is an integer in a series X, Y, Z, for Z<Y.

In an embodiment, the multimedia data is divided into the one or more packets based on time frame of the multimedia data. For example, consider a multimedia data of total time frames of 120 seconds (s). Here, let each time frame be 1 s. Thus, there are 120 time frames. Let the time frames 1 s-30 s correspond to P1, time frames 30 s-40 s correspond to P2. Likewise, each packet P_(N) represents a range of time frames K-120 s, where K represents a time frame between 1 s and 120 s.

In an embodiment, the one or more network interface 101 may include, but is not limited to cellular network, Wireless fidelity (Wi-Fi) and Bluetooth tethering. In an embodiment, the media device 100 may include but is not limited to a Personal Digital Assistant (PDA), laptop, cellular phone, tablet and any other computing device comprising plurality of network interfaces 101.

In an embodiment, the media device 100 may receive the one or more packets from the media server 104 either through wired interface or wireless interface. In one embodiment, wired interface may include but is not limited to Ethernet, fibre optics and twisted pair cables. In one embodiment, wireless interface may include but is not limited to laser communication, Infra-Red (IR) communication and Radio Frequency (RF) communication.

FIG. 2 illustrates internal architecture of the media device 100 in accordance with some embodiments of the present disclosure. The media device 100 may include at least one Central Processing Unit (“CPU” or “processor”) 203 and a memory 202 storing instructions executable by the at least one processor 203. The processor 203 may comprise at least one data processor for executing program components for executing user or system-generated requests. The memory 202 is communicatively coupled to the processor 203. The media device 100 further comprises an Input/Output (I/O) interface 201. The I/O interface 201 is coupled with the processor 203 through which an input signal or/and an output signal is communicated.

In an embodiment, data 204 may be stored within the memory 202. The data 204 may include, for example, request data 205, interface data 206, packet data 207 and other data 208.

In one implementation, the request data 205 includes, but is not limited to, format of the multimedia data, size of the multimedia data and time frame of the multimedia data.

In one implementation, the interface data 206 may include, but is not limited to, number of network interfaces 101 available in the media device 100, type of network interfaces 101 and the one or more bandwidth parameters of the network interfaces 101. Here, the one or more bandwidth parameters may include, but is not limited to, bandwidth size, bandwidth speed, latency, throughput jitter and error rate.

In an embodiment, the packet data 207 may include, but is not limited to, number of data packets the multimedia data is divided into, time frame corresponding to each data packet and allocation information of the data packets to the one or more network interfaces 101.

In an embodiment, the data 204 in the memory 202 is processed by modules 209 of the media device 100. As used herein, the term module refers to an application specific integrated circuit (ASIC), an electronic circuit, a field-programmable gate arrays (FPGA), Programmable System-on-Chip (PSoC), a combinational logic circuit, and/or other suitable components that provide the described functionality. The modules 209 when configured with the functionality defined in the present disclosure will result in a novel hardware.

In one implementation, the modules 209 may include, for example, communication module 210, identification module 211, allocation module 212 and other modules 213. It will be appreciated that such aforementioned modules 209 may be represented as a single module or a combination of different modules.

In an embodiment, the communication module 210 receives a request from a user for streaming a multimedia data on the media device 100. Also, the communication module 210 receives the one or more packets from the media server 104 through the one or more network interfaces 101.

In an embodiment, the identification module 211 receives an indication from the communication module 210 regarding the request from the user. Then, the identification module 211 identifies the one or more network interfaces 101 available in the media device 100. In an embodiment, a network interface 101 may be present in the media device 100, but may not be available for streaming the multimedia data. In such scenario, the identification module 211 may not identify the network interface 101. The identification module 211 may generate a log for storing the identified one or more network interfaces 101.

The allocation module 212 receives the request data from the communication module 210 and the interface data 206 from the identification module 211. Further, the allocation module 212 determines the one or more bandwidth parameters of each of the one or more available network interfaces 101. Further, the allocation module 212 allocates one or more packets to each of the one or more network interfaces 101 based on the bandwidth parameters. The allocation information of the one or more packets to each of the one or more network interfaces 101 is stored as the packet data 207 by the allocation module 212. The allocation module 212 provides the packet data 207 to the communication module 210 for requesting the one or more packets over the allocated one or more network interfaces 101.

In an embodiment, the other modules 213 may include, but are not limited to, buffering module, media parser module and media player module. The media parser module provides information about quality of multimedia data, size of the multimedia data and duration of the multimedia data. In an embodiment, the buffering module receives the one or more packets from the allocated one or more network interfaces 101. Further, the one or more packets are collated by arranging header of the one or more packets in sequence to form the multimedia data. Then, the buffering module provides the multimedia data to the media player module for streaming.

FIG. 3 shows a block diagram illustrating data flow in accordance with some embodiments of the present disclosure. As shown in the FIG. 3, the multimedia data is received by the media device 100 from the media server 104. Here, the multimedia data is received as one or more packets from the media server 104. Further, the one or more packets are distributed among the one or more network interfaces 101 of the media device 100. The network interface 101 ₁ represents a Wi-Fi network and the network interface 101 ₂ represents a cellular network. Considering that the Wi-Fi network 101 ₁ has more bandwidth speed compared to the cellular network 101 ₂, line connecting the media server 104 to the Wi-Fi network 101 ₁ illustrates that more number of the one or more packets are received through the Wi-Fi network 101 ₁ and less number of packets are received through the cellular network 101 ₂. Thus, the one or more packets are received through the one or more interfaces 101 for streaming the multimedia data.

FIG. 4 shows a flow chart illustrating a method for adaptive streaming of multimedia data, in accordance with some embodiments of the present disclosure.

As illustrated in FIG. 4, the method 400 may comprise one or more steps for adaptive streaming of multimedia data, in accordance with some embodiments of the present disclosure. The method 400 may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform particular functions or implement particular abstract data types.

The order in which the method 400 is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the spirit and scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.

At step 401, the communication module 210 receives a request from a user for streaming the multimedia data. Here, the user may provide information about the multimedia data. The information may include, but is not limited to, name of the multimedia data, format of the multimedia data and quality of the multimedia data. The request is transmitted to the media server 104 and in return receives a response from the media server 104. The response may indicate, but is not limited to, an acknowledgment for the request made and packet data 207.

At step 402, the identification module 211 identifies the one or more network interfaces 101 available in the media device 100. The identification module 211 may store identified network interfaces information in a log. The log may include, but is not limited to, type of the one or more network interfaces 101, availability of the one or more network interfaces 101 and bandwidth size of the one or more network interfaces 101.

At step 403, the allocation module 212 allocates the one or more packets to the one or more network interfaces 101. The allocation module receives the packet data 207 from the communication module 210 and the interface data 206 from the identification module 211. The allocation module 212 determines the one or more bandwidth parameters of each of the one or more network interfaces 101. Particularly, the allocation module 212 calculates bandwidth speed of the one or more interfaces 101. In a non-limiting embodiment, the bandwidth speed is determined by receiving a sample data from the media server 104 on each of the one or more network interfaces 101. Further, time taken by the sample data to reach the media device 100 is determined. Then, the speed is calculated as shown below:

Bandwidth speed=Amount of sample data/time taken to reach media device from media server  (1)

In Equation 1 the amount of sample data is measured in bytes and the time is measured in seconds. Further, the bandwidth speed is measured in bits per second (bps). For illustration, let us consider 1 Mbyte of sample data is requested from the media server 104. Let the time taken by the sample data to reach the media device 100 be 3 s. The bandwidth speed is calculated as:

$\begin{matrix} {{{Bandwidth}\mspace{14mu} {speed}} = {\left( {1\mspace{14mu} {MB}*8} \right)\text{/}3\mspace{14mu} s}} \\ {= {2.666\mspace{14mu} {Mega}\mspace{14mu} {bits}\mspace{14mu} {per}\mspace{14mu} {second}\mspace{14mu} ({Mbps})}} \end{matrix}$

The bandwidth speed is calculated for each of the one or more interfaces 101 using Equation 1. For illustration, let us consider three network interfaces 101, namely first interface 101 ₁, second interface 101 ₂ and third interface 101 ₃. Let the bandwidth speed of the first interface 101 ₁, the second interface 101 ₂, and the third interface 101 ₃ be 0.8 Mbps, 1 Mbps and 3 Mbps respectively. Further, bandwidth speed required for receiving the multimedia data on the one or more network interface 101 is determined as given below:

B/W speed of Interface N for receiving multimedia data=Calculated speed of Interface N*(Total speed required to receive multimedia data/Summation of calculated speed of Interface 1 to Interface N)  (2)

The Equation 2 provides bandwidth speed of each of the one or more interfaces 101 for receiving the multimedia data. From the above illustration, let the total bandwidth speed required for receiving the multimedia data be 3.5 Mbps. The summation of calculated speed of the first interface 101 ₁, second interface 101 ₂, and the third interface 101 ₃ is 0.8 Mbps+1 Mbps+3 Mbps=4.8 Mbps. The bandwidth speed for the first interface 101 ₁, second interface 101 ₂, and the third interface 101 ₃ for receiving the multimedia data is calculated as follows:

First Interface=0.8 Mbps*(3.5 Mbps/4.8 Mbps)=0.59 Mbps

Second Interface=1 Mbps*(3.5 Mbps/4.8 Mbps)=0.73 Mbps

Third Interface=3 Mbps*(3.5 Mbps/4.8 Mbps)=2.18 Mbps

From the above calculation, it evident that the third interface 101 ₃ has more bandwidth speed compared to first interface 101 ₁ and the second interface 101 ₂. Thus, more number of the one or more packets are allocated to the third interface 101 ₃. Likewise, the second interface 101 ₂ has more bandwidth speed compared to the first interface 101 ₁. Thus, the second interface 101 ₂ is allocated more number of the one or more packets than the number of packets allocated to the first interface 101 ₁. In an embodiment, the one or more packets may be allocated as shown in FIG. 1B. For example, packet P1 and packet P2 may be allocated to the first interface 101 ₁ Similarly, packet P3, packet P4 and packet P5 may be allocated to the second interface 101 ₂. Similarly, packet P6, packet P7, packet P8, packet P9 and packet P10 may be allocated to the third interface 101 ₃.

At step 404, the communication module 210 requests the one or more packets over the allocated one or more network interfaces 101. Further, the communication module 210 provides the one or more packets to the media buffer 102. The media buffer 102 collates the one or more packets by arranging the header of the one or more packets in a sequence to form the multimedia data. Then, the multimedia data is provided to the media player 103 for streaming.

In an embodiment, the multimedia data can be divided into the one or more packets based on data segments. For example, consider a multimedia data of 1 MB (1000 KB). 1 MB of the data can be divided into 3 packets. First packet may represent 600 KB of the multimedia data, a second packet may represent 300 KB from remaining 400 KB and a third packet may represent 100 KB.

In an embodiment, the one or more interfaces 101 are monitored by the media device 100 at predefined intervals of time.
